I take my chipped Mazda key (no buttons) with me in my bathing suit pocket under my wetsuit when I dive. It still works fine, but I tend to stay shallow (20 ft or less, but have taken the key down to 70+ feet). I've got a third "spare" so if the one I dive with ever dies I can get a new one cut...

What do they do with all the tails after they confiscate them? Throw them away?

Silicone - silicone rubber, you could call it crosslinked polysiloxane if you want to sound fancier. Plastic could be polycarbonate or acrylic, but that's really just a guess. It would be worth calling a couple manufacturers and seeing what they tell you.

Welcome, and best of luck to you! There's a "used vs. new gear" debate that flares up on here form time to time, and a good discussion of things to consider when buying used can be found in this thread: Please wait. I've bought almost all of my major gear used (regulator, BC, tank, computer...

Gold Coast Scuba in LBTS always tops off my HP 120 to 3,500 psi provided I leave it long enough for it to cool and have it topped off. If I'm not able to give them enough time to cool down and top off when I get the fill, they've done it for me if I swing by on the way to the dive site.

I think changing a lot of the specialty "certifications" to specialty "courses," and limiting C-cards to only the core-type courses that cover broad classes of dives and the gas mixes that you breathe would be a positive step. You'd get "certified" for things like OW, AOW, Rescue, Nitrox, Tech...

I just started wearing a lycra skin underneath my 3 mm wetsuit. I was having some issues with it rubbing on the side of one of my ankles and a part of my neck, and the skin has helped a lot with that. I didn't notice that much of a difference getting the wetsuit on, but it was a little easier to...

From one of the articles I read, it looks like one of the rescue dive team members is being personally sued. I'd be very interested in hearing from anyone with a legal background out there whether the decision in this case may affect liability for non-professionals attempting a rescue. FWIW I...

Second on the sea emperor, and also suggest the Ancient Mariner. These were my first two wreck dives ever.

I agree. Brooks Brothers wool compresses too much at depth anyway. :eyebrow:

American science and surplus is a good place to source an electric motor that may do the job (and is just a cool place in general) - American Science & Surplus : Items Just Off the Truck At one time, they had a motor with a gear reducer drive that could be just the ticket for tumbling a tank...

Out of curiosity, were air-integrated dive computer consoles developed before ones that rely on a wireless link to transmit pressure information, or were they developed simultaneously?

I've heard Red Reef Park in Boca Raton, FL is a good place for this. One of my friends used to go there with his family, including children that were 3-6 years old. I've not been there myself, though. The seas in this area can range from glassy calm to shoulder high surf, with calmer weather...

I recently switched from Oceanic Vipers to Mares Avanti Quattros. The vipers were just too floppy for me, and I can "kick and glide" in the quattros more effectively and feel like I have more control in the water with them.

There are lots of reefs and artificial wrecks in the Fort Lauderdale area at depths ranging from 12 feet to over 100 feet. A few sites can be reached from the beach, and most others are a relatively short boat ride from shore. Here's a video shot by one of the locals (K. Porter) of a shore...

To give you some reference points, I recently sold a steel Sherwood HP-80 with a brand new hydro and VIP for $170, and it went fast (like, within a day or so) and I got full asking price. A friend who had gotten out of diving gave me that tank, which had sat (pressurized) in a garage since the...

As much as I don't want to be fair to the boater - I've done most of my dives (however few) with groups of anywhere from 4-20 people - and sometimes it's rather difficult to see diver's heads (let alone bubbles) above the water, even when specifically looking for them in relatively calm...

I'm not a commercial diver, but I'm in the engineering/construction industry and have some basic training on OSHA and confined space entry. If I'm interpreting what I've read correctly, OSHA has separate standards that relate to diving that would seem to apply in your case. Unless Georgia has...

I dive a full 3 mm year round down here, but my dives tend to be shallow and I usually don't dive on consecutive days or do more than 1-2 dives in a day. Edit: I am the kind of person who tends to not get cold that easily.

I look at swellinfo.com, magicseaweed.com, and a local beach cam the day of the dive. If you start to see whitecaps on the beach cams, it's an indication that things are starting to get sporty. On swellinfo, if you're looking for the calmest days you probably want to shoot for knee high surf or...
